Bob Nystrom fe143644b3 Rationalize string lengths.
The .count getter on string returns the number of code points. That's
O(n), but it's consistent with the rest of the main string API.

If you want the number of bytes, it's "string".bytes.count.

Updated the docs.

Fixes 68. Woo!

Bob Nystrom 72c38a59ce More stuff for working with strings and bytes!
- "\x" escape sequence to put byte values in strings: "\x34"
- String.byteAt(index) gets value of byte in string.
- String.bytes returns a raw sequence of bytes for a string.
- String.codePointAt(index) gets the code point at an offset as a raw number.

Bob Nystrom 7d45dda383 String.fromCodePoint(). Fix #219. 2015-03-27 07:43:36 -07:00
Bob Nystrom eb424f5c1a Make strings iterable over their code points.
I'm not sure why, but this also regresses perf:

binary_trees - wren            ..........  3290  0.30s   96.68% relative to baseline
delta_blue - wren              ..........  7948  0.13s   99.06% relative to baseline
fib - wren                     ..........  3165  0.32s   95.90% relative to baseline
for - wren                     ..........  8242  0.12s   96.00% relative to baseline
method_call - wren             ..........  5417  0.18s   78.74% relative to baseline

Need to investigate.
